Pa gur

Poem 31 of the Black Book of Carmarthen, a mid-13th century manuscript, is known from its first line as Pa gur yv y porthaur? (meaning "What man is the gatekeeper?") or Pa gur, or alternatively as Ymddiddan Arthur a Glewlwyd Gafaelfawr ("The dialogue of Arthur and Glewlwyd Gafaelfawr").^[1][2][3] It is a fragmentary, anonymous poem in Old Welsh, taking the form of a dialogue between King Arthur and the gatekeeper Glewlwyd Gafaelfawr, in which Arthur boasts of his own exploits and those of his companions, especially Cai the Fair.^[4] Pa gur is notable for being one of the earliest vernacular Arthurian works, and for alluding to several early adventures of Arthur which are now lost.^[5] Its precise age is not known and has been the subject of wide-ranging disagreement, but scholarly opinion now tends to favour a date of c. 1100.
